To all 'whom it may concern:

Be it known that I, HARRY H. Wns'r, a citizen of the United States,residing at Plymouth, in .the count of Luzerne and State ofPennsylvania, rave invented certain new and useful Improvements inCircular-Knitting Machines; and I do declare the following to be a full,clear, andexact description of the invention, such as will enable others.skilled in the .art towhich it appertains to make and use the same.

This invention relates to circular knitting machines adapted to knitcomplete seamless and striped stockings witlrlieel and toe tips composedof a different yarn and in which all the operations are accomplishedautomatically. l

The object of the invention is to provide simple and eflicient means foroperating the yarn changers by means of which the thread can beaccurately changed to obtain any desired pattern.

With these and other objects in view, the invention consists .of certainnovel features of construction, combination and arrangement of partsaswill be more fully described and particularly pointed out inthe appendedclaims.

described. vThis clutch is adapted to be moved either to the right or tothe left to cause it to engage certain vgears when certain parts to bedescribed are operating. A gear 10 is mounted on the shaft 2 and has asleeve 11 at its outer end extending to the outer end of said shaft 2and on which the fast pulley 3 is revolubly mounted.. The hub of thisgear 10 also has a clutch member 10 on its inner face for engagementwith the sliding clutch 8 for a purpose to be described.

The slow pulley 4 is mounted on the sleeve 11 and has a sleeve 12extending to the end of the shaft 2 on which the loose pulley 5rotates.A The sleeves 11 and 12 of the gear 10 and pulley 4 are fixedtogether by means of a ke 6' formed integral with the handle 6, saihandle being secured to the sleeve 11 of gear 10 preferably by means ofpins as 6 s is clearly shown in Fig. 34.

A gear 13 is -made integral with the fast pulley 3 and is adapted tomesh with a inion 14 carried by a stub' shaft 15 mounted in suitablebearings in the frame 1 and having a larger gear 16 at its otherendwhich meshes with the gear 10 on the shaft 2. A gear 17 is looselymounted on the shaft 2 and is provided on its' inner face with a clutchmember 17 for engagement by the clutch 8 and is designed for a purposehereinafter described. i

' A driving belt 18 is designed to operate on any one of the pulleysabove referred to and a belt shifter 19 is connected to the frame andadapted to operate automatically to shift the belt onto the desiredulley. The free end of this shifter 19 exten s into the path of anoperating cam diskv20 which is shown in detail be hereinafter furtherdescribed. This belt shifting member 19 (see Fig. 1) has aklateraloutwardly extending arm 19 provided with longitudinally spaced pins419aL which normally engage the belt 18 and when the shifter member 19is moved outward or inward the desired distance by the cam disk 20 itcarries the belt with it and shifts 'it to the desired pulley. lThismember 19 also has a lateral inwardly extending arm 19b lprovided with alug 19c designed to engage the frame l to limit the outward swing of theShifter member 19. This arm 19" is also provided in its upper face witha notch or recess 19d adapted to be engaged by a pawl 19e for lockingthe shifter in position to hold the belt on the loose pulley 5. An arm19t extends inwardly from the member 19. through suitable bearings ofthe frame 1 and has a collar 19g fixed thereto between which and the frame on `said,arm is a coiled spring 19h designed to hold the free endof the member 19 yieldably in engage'- ment with the operating cam disk20. This belt shifter cam disk 20 which is fixed to one .or oscillatingof the member 157.

end of a shaft 90 and is shown in detail'in' Fig. 71 is provided on oneface thereof with laterally extending cams 20a, 20 'and20 with spaces20", 20d and `20f formed between them and the free lower end 19 of thebelt shifterdever 19 extends into the path of this cam disk and isoperated by said cams to move the' lever and shift the belt in themanner now to be described. y When the machine is operating to knit theleg of a stocking, the belt 18 is in position on the fast pulley 3 andthe end 19 of the shifter lever 19 engages the fiat face of the disk 20in the space 20t between cams'20e and 20a (see Fig. 71). When the leghas been completed and the parts to be described have been actuated tothrow the machine -on theheel the cam disk 20 is turned with theshaft`90 to cause the end 19 to ride up the incline 20a of the cam 20into'contact with its outer face or edge whereby the shifterl member 19is moved outwardly carrying the belt with it and shifting it onto theslow pulley 4 in which position .it remains during the knitting of theheel. When the machine passes from the heel to the foot the disk 20 isturned sufficiently to causet-he lever end 19 to drop ofi' the cam 20ainto the space 20b which moves the shifter 19 inwardly a suiiicientdistance to shift the belt onto the fast pulley 3 again where it remainsduring the knitting of the foot. The machine is then thrown onto the toeandthe end 19 nieves up the incline 20h of the cam 20c into engagementwith the face of said cam thereby moving the shifter 19 outward againand transferring the belt to the slow pulley 4 where it remains untilthe toe is completed when the further turning of the disk 20 causes theend 19 to dro olf -cam 20c into the recess 20d to again shift the beltto the fast pulley 3 to form the several waste courses known in the artas the loopers rounds. When these courses are finished, the furtherturning of the disk causes the lever end 19 to move up the long cam face20e which moves the lever 19 outward to its extreme limit and shifts thebelt ontol the loose pulley 5 and the machine is thrown out ofoperation.

A depending bracket v21 see Figs. 1,-3, 7

and 8) is mounted on the ase plate l. `of the frame 2 and is similar inconstruction to thatv shown in my pending application iled Oct. 12,1908, Serial No. 457,380. A large gear wheel 22 is journaled on a studheld 1n said bracket 21 and carries a pattern ring 23, which latter ringwill be hereinafter described in detail. The pattern ring 23 (see Fig.32 is removably mounted on the free side o the gear 22 preferably bmeans of screws and this ring ispreferab y provided with anapertureadapted to engage a pin mounted on the wheel 22. It will thus be patternring may be readily removed from the gear wheel 22 and a ring bearing adiderent pattern substituted therefor when desired. This attern which isiP an annulus (see Figs. 3 and 10) is provided on its periphery with aplurality of notches or recesses of different lengths and depths whichare adapted to control the ordinary yarn changing controllers whichlatter will not b described in detail as they form n'o part of thepresent' invention. These recesses are formed in as many depths as'thereare colors of yarn to used, three being shown in the present instance.The pattern can be quickly changed by removing one 'ring 23 andsubstituting another and with any suitable distinguishing marks by whichthey may be known. The firsty notch or recess shown in the periphery aof the pattern ring herein illustrated is designated as b, the secondnotch as c and the third notch as d. These notches or recesses aredesigned to be engaged by a pin or stud 24 connected with a lever 25(see Figs. 3, 12 and 13) which is fulcrumed near its lower end at 26 ona bracket 27 bolted to the lower face of the base late 2 of the frame 1.This pin 24 is pre erably detachably mounted in a block 28 (seeFig. 17which is suitably mounted at the free end of an extension 27 of bracket27, it being preferably held by a plate 28 secured by screws as 28".Astud 29 is screwed into block 28 and extends into a slot 25a arrangedin a block 25" mounted in an opening 25 in the lower end ofy the lever25. This block 25a is adjustably held byY screws as 25d which passthrough the end of the lever 25. These scre "s are held against movementby -jam nuts 25e. The upper end of this lever 25 (see Figs. 3, 12`and14)f has an inclined guide or raceway 3'0 designed to said rings may beprovidedvso receive a sliding roller 81 which will be hereinafterdescribed. A laterally extending lug 31 projects from the outer edge ofsaid lever on the cam ring 25 at a point below the guide 30 with a spaceformed between them in which a nember 7 8 hereinafter described isdesigned to operate. The upper face of this lug 31 is inclined as shownat 31 and a pin 31* extends laterally from one face thereof and isadapted for a purpose to be described? The attern ring 23 is alsoprovided in its periphery Awith spaced notches 32 and 33 much deeperthan the notches b, c and (l and are designed to receive t-he pin 24 atpredetermined intervals to throw into operation certain yarn changers toprovide for the formation of the tip of the toe and heel in a differentcolored yarn. This pattern ring 23 is also provided on one face thereofwith a long arc-shaped cam 34 and with cams 35 and 36 arranged at properdistances on said ring to throw into operation certain mechanismhereinafter described. -These ca-ms 35 and 36 are .provided on theirupper faces near one end with raised portions` or lugs 35 and 36 for apurpose to be described. Two removable headed studs or screws 37 and 38are also arranged and are adapted to operate certain mechanismhereinafter described for forming extra courses such as are used inmaking full length hose. The heads of these studs extend in a plane beond the cams on the ring to permit the mem er which is operated by thecams to ride thereunder without being actuated thereby.

A shaft 51 is mounted in a bracket 21 bolted to the lower face of thebase plate 2 andinan apertured ear 2lbextending laterally from thebracket 21. and 25.) A pinion 39 is fixed to the shaft 51 at one endthereof and is arranged to mesh with and drive the gear 22 which carriesthe pattern ring 23. A ratchet wheel is removably secured to the otherend 'of the shaft 51 preferably by a key 52 to provide for its readyremoval and the substitution of another wheel having a different numberof teeth when it is desired to change the size of the stocking to beknit. v

A guard 53 made in the form of a disk having a recess 54 in itsperiphery (see Fig. 24) 'is made integral with one end of a sleeve 55which encircles the shaft 51 and said guard is arranged adjacent thevinner face of the ratchet 50 the peripher of said disk extendingslightly beyon the teeth of the ratchet wheel 50 and is designed to holdthe ratchet actuating pawl out .of engagement with the teeth of saidratchet Wheel, at predetermined intervals as will be hereinafterdescribed. This sleeve is preferably made in two sections (see Fig. 25)having a clutch-like connection to provide for the ready assembling ofthe parts. -A collar 56 is mounted on the sleeve 55 and has an arm 57extending laterally therefrom. A spring 58 is coiled around the sleeve55 between the bracket 21al and said collar and has one end (See Figs.1, 3.

the pawl 41 ratchet guard outer end secured to said bracket and theother end engaged with said arm 57 and has a tendency to force said armnormally downward. arm 58 has one end en sleeve 55 for a purpose to edescribed.

A pawl 41 for actuating the ratchet wheel 50 is fixed to the outer endof a stub shaft 41' which extends laterally from the lower lAn ged withsaid end of a pitman 40 and the other end of the arm 58 is also engagedwith said tub shaft between the pawl 41 and the pitman (see Figs. 18 and20). A sprin 49 1s connected at one end to the free end o the pawl 41and at its other end to said link 40'* to hold said pawl yieldably inengagement with the ratchet wheel 50. The itman 40 carries near itslower end a stu 40b (see Figs. 18 and 15)) .and the upper end thereof ispivoted eccentrically to the gear wheel 7 on the driving shaft. 2, thestud forming a pivot for a lever to be described. This pawl 41 ispreferably made adjustable to provide for wear thereof and as shown inFigs. 18 and 23 comprises a stem' or shank 42 having an elongated slot43 therein through which the bolt 44 passes to connect the head 45 ofthe pawl therewith. This head 45 is preferably bifurcated as shown inFig. 22 with the shank 42 extending between the arms of the forked endand these arms are rovided with bolt apertures re 'stering wit toreceive the bo t gaged with the free end of the stem 42 and has anenlarged head 47 which extends over and engages the' upper faces of thearms of the forked end of the head 45 to hold the head and stem firmlytogether and prevent pivotal movement of one relative to the other. Aset screw 48 extends through the end of the head 43 and engages theshank of the screw 46 to lock it against turning. The recess 54 (seeFig. 24) formed in the periphery of the guarddisk 53 ermits the toe ofthe pawl 41 to normally rop therein in position to engage and operatethe ratchet wheel 50 whereby the pattern ring is actuated. The head ofthe pawl 41 as shownl clearly in Fig. 2 is made suiicientl wide to spanthe periphery of both the'ratc et wheel 50 and' guard disk 53 andoperates said ratchet wheel only when the toe thereof rests in therecess 54. When it -is desired to throw the pattern wheel out ofoperation the unnotched portion of the periphery of the guard disk iscaused to pass under the toe of the awl 41 and raise it out ofengagement with the teeth of the ratchet Wheel 50, by means now to bedescribed.

The guard 53 which elevates the toe of is actuated by the followingmechanism; to wit, the arm 57 which extends laterally from the sleeve 55of the 53 has an upright arm 58 pivotally connected at its lower endwith the of said arm 57 and at its upper made the slot 43` 44. A screw46 is en-A end with the free end of a horizontal bar 59 the other end ofwhich is made integral with a shaft 60 journaled on suitable bearings 61and 61, in the frame 1 (see Figs. 2 and 69). Another arm 62 made interal with the o posite end of the rock sha t 60 extends forwardlytherefrom and is provided at its free end with two rollers 63 and 64arranged on opposite sides thereof. These rollers 63 and 64 are arrangedin position to be engaged by certain cams 102 and 96 hereinafter `to bedescribed whereby the arm 62 is depressed the shaft 60 rocked on itsbearing and the motion is transmitted through the bar 59, arm 58', andarm 57 to turn the sleeve 55 of guard 53 and turn said guard to causeits periphery to enga e the toe of the pawl 41 and disengage it from theratchet teeth of the wheel 50 and thereby'throw the pattern ring gut ofoperation. The bearings 61 and 61a for the shaft 60 are preferably madein the form shown having pointed ends engaging sockets in the end of theshaft 60. The member 61a is preferably made in the form of a screw toadapt it to be adjusted to provide for Wear of the parts.. The member 61is constructed in the form of a pointed stud having one end mounted inthe housing and with a flange 61b arranged near its pointed end toprovide a space between said flange and the housing to permit an extracourse operating lever 126 to be pivotally' mounted on said stud at thispoint.

The yarn changing mechanism for striping the leg and foot which isactuated by the pin 24 engaging the various recesses b, c and d in theperiphery of the pattern ring 23, as shown, comprises three actuatorlevers 65, -66-and 67shown in detail in Figs. 26, 27, 28,29, 30 and 31.These levers are provided with laterally extending pins as 65a, 66a and67a, respectively, the free ends of which lie in the same vertical planeand are designed to be engaged by an operatinga arm hereinafterdescribed which is disposed to engage one of said pins on each actuationthereof whereby the upwardly extending nose or lug at the free end ofthe lever or finger so moved passes out of engagement 'with the inclinedface 688L formed on one end of an approximately arc-shaped member 68,one of which is arranged above each thread changer actuator lever and ispivot-y ed intermediately of its ends. The other ends of said members 68are connected with wires as 69 for actuating the yarn changerswith-which they are connected. The free outer ends of these members 68which are provided with the downwardly inclined lower faces are adaptedfor engagement by the lugs on the thread changer actuator levers wherebysaid ends are tilted .upwardly to lower their other ends and throw theyarn changers with which they are connected out actuator levers is ofthe same general shape, the upwardl extendn lugs 65h and 66b being of dierent lengis and the lengths of the long'arms of' said levers being alsoditerentto provide free spaces for the studs 65 and 66a and 67a indierent planes vertically spaced one above the other. These levers areloosely mounted on a shaft 90 and are each provided with a laterallyextending a rtured ear, as 70 with which a coiled spring as 71 isconnected at one end and at its other en'd with an ear as 72 on theframe 1, to exert a forward pull on its lever and cause its free upperend to ride forward under the outer end of its member 68 into engagementwith the inclined face 68 of said member to throw and hold itsrespective yarn changer out of operation. These levers are also eachprovided with hook-'like noses as 73, at their lower pivoted ends, whichare adapted to be successively engaged with a pawl on the spring pressedtrip member or tri ger 74,- pivotally mounted on the frame l see Figs.3, 26, 32 and 32a), adapted to hold them in operative position foroperating their respective yarn changers. This member 74 is preferablyconstructed as shown in detail in Figs. 32 and 32, with a stud 75extending laterally from one side edge for en agement by a. memberhereinafter describe to disengage it from the nosel of the lever whichis left in engagement with said trigger member on the completion of thestocking. This member 74 is pivotally mounted on a stub shaft 74 securedto the housing and is yieldably held in operative position by means of acoiled spring 74b engaged at one end with an apertured ear 74e whichextends rearwardly from said member 74 and at its other end is connectedto the housing and the 'upper face of its free the yarn changercontrollers are thrown out of operation. It is, however, necessary thatthe movement of these thread changer levers shall not be independent ofeach other, but that they shall be so connected that the depression ofany one of the thread changers t0 operative positionl to feed yarnnecessarily brings about the raising of any other one which has beenpreviously depressed but not until after the incoming thread changer hasreached its operative position. This is eifected by the trigger 74 asfollows: The tripping extremity of the trigger.v 74 having the beveledupper face is so related to' that of the noses 73 of the thread'changeracthator levers that when any -one ofthem is moved to depress its threadchanger, its nose 73 presses aglinst the beveled surface of the trig erpus ing it against the s ring 74b until te hook portion thereof isisengaged from the nose of the lever already in engagement therewithwhich is released and under the tension of its spring 71 moves itsthread changer into inoperative osition and the nose of the lever beingmove is engaged with the hook of the trigger and fixed in this positionuntil the trigger is again moved.

A bar 75a (see Figs. 3, 26 and 33) is fas- 4 tened at one end to thehousing and extends in a plane below the apertured ears 7 0 of thelevers 65, 66 and 67 and is provided with three vertically adjustablepins 7 5b, 75c and 75d arranged respectively in the paths of the ears as70 of the .three levers to form stops for limiting the forward movementof said levers. Set screws as 75e ,extend through said bar 7 5a andengage the respective pins to hold them in adjusted position. The meansfor operating these levers 65, 66 and 67 shown in Figs.' 3, 63, 64, 65,comprises an obtuse angled lever 76 fulcrumed'at 76a to the housing andhaving one end slotted lon` gitudinally and pivotally connected with thestud b on itman 40 (see Fig. 3) and the free end of e lever 76 has alateral eX- tension 77 a provided with a roller 78 designed to engagethe cam shaped recess formed between the inclined race-way 30 and thelug 31 of the lever 25. An upright bar or link 79 is pivotally connectedto the free `end of the extension 77a of the bar 77 adjacent the roller78 and is provided on its end with an upwardly inclined arm or finger 80which is adapted to operate in the path of the pins of the levers 65, 66and 67 for throwing them into position to operate their respective yarnchangers. A 'roller 81 is mounted on .the upright bar 79 preferably at apoint adjacent its inclined finger 80 and this roller is designed tooperate in the inclined race-way 30 of the free end of the lever 25which carries the pin 24 at its other end-for engaging the recesses inthe periphery of the pattern ring. A spring 25 is arranged to bearagainst the lever 25 to force it normally outward away from the frame 1to cause the pin 24'l to yieldably engage the periphery of the patternring. Then the in 24 dro s into one of the recesses b an c or d o thepattern ring, the

. free end of the lever 25 carrying the raceway 30 is moved downwardlyand held stationary to so position the raceway 30-that the motionupwardly of the link 79 and roller 81 due to its connection with thepit-l man 40 will cause the linger 80 to be projected inwardly in a pathdetermined by the position of the raceway 30and the linger 80 willcollide with one of the pins 67 66a or 65a to actuate the selected yarnchanger.

The deepest notch in the pattern wheel will position the raceway 30 soas to cause the pin 67a and lever 67 to be moved while the shallowestnotch will eect moving of the lever 65, but the periphery of the patternwill cause the finger 80 to take a path too low to actuate any of thepins. The downward motion of the lever 76, rollers 78 and -81 retractsoutwardly the finger. 8() and through `the roller 78 acting on the camlug 31 near the end of its downward motion lifts the in 24 from theperiphery ofthe pattern w eel which now can be againadvanced. The yarnlast selected will remain in operation until another notch in thepattern wheel comes under the pin 24 the motion of the finger 80 beingon the lower path and out of engagement with the pins and the yarnchanger actuator levers so long. as the in 24 ri es on the periphery ofthe whedl.

A segmental gear 82 is carried at the free end of oner arm of a bellcrank lever 83 which is fulcrumed at 84 to the frame 1 and this gear 82meshes with the pinion 17 on the shaft 2. The free end of the other'armof said lever 83 is pivotally connected with a pitman 85 connected witha gear 86 which meshes with and is o erated by the pinion 10 (see Fig.4)'. This pitman 85 operates the bell crank lever 83 and rocks it backand forth for a purpose to be described.v

Three pawls 87, 88 and 89 are pivotally mounted on a laterally extendingstub shaft 83 carried by the upright arm of the bell crank lever 83 andthese pawls are designed to operate under certain circumstances ratchetsdriving the controlling cams on the shaft 90. The pawl 87 has an arm 87eX- tending upwardly therefrom which is designed to be engaged by ayieldable member hereinafter described. Three toothed wheels 91, 92 and93 are mounted adjacent to each other on the shaft 90 which is journaledin the frame l and on which the clutch opera-ting disk or drum 155, thebelt shifting cam disk 20, the picker operating cam disk, and the levers65, 66 and 67 are all mounted, two of said toothed wheels 91 and 93'andthe three levers 65, 66 and 67 being revolubly mounted on said shaft andthe other toothed wheel 9.2, the clutch operatingk cam disk 155, thebelt shifter disk 2Q and the picker operating disk being fixed to theshaft by' any suitable means and adapted to be turned with said shaft aswill be hereinafter described.

A spring 87b is coiled around the hub of the pawl 87 and has one endattached to a screw 87c which extends through the lever 83 and fastenssaid stub shaft 83 firmly in place. The other end of this spring 87"bears on the up er face of the shank of the pawl 87 and ho ds ityieldably in operative position to insure ,a positive engagement of saidpawl with the teeth of the wheel 92. The other pawls 88 and89 operate bygravity as they are longer than pawl 87 and require no spring.. The toeof lpawl 87 is made sufliclently Wide to provi periphery of wheel 92 andan L-shaped lever 142 now to`be described. The upright short V arm 142aof this lever has a laterally extendfree end o the rod 144 operatespiston-like in a ,cylinder 145 having a cushionlng spring 146 arranged,in said cylinder between the free enlarged end of the rod V'144 and theclosed outer end of the cylinder, the` cylinder being movable on the rod144. This yielding cylinder is adapted to be engaged by the 'u right arm87 of the pawl 87 and is made yieldable to prevent breakage of the artswhen they come in contact. A finger 14' extends from the short arm ofthe lever 142 in' position to engage a pin 91b on the ratchet wheel 91to act as a safety guard for holding the lever 1;42 under the pawl 87and prevent `its engagement with the teeth of the wheel 92 until theproper mechanisms have been operated. When the pawl 87 swings forwardthe upright arm 87 thereof engages the cylinder 145 and swings the lever142 on its fulcrum and lifts the free end of its long arm out ofengagement with the head 138 of lever 136 and permits said lever underthe action ofits spring 137 toswing back into position ready for thenext operation.

The ratchet wheel 91 which is revoluble on the shaft 90 is provided onits periphery with the usual ratchet teeth of uniform size having onetooth 91 longer than the rest,-

and a block 94 secured to the casing or frame 1 has a laterall extendinginclined portion 95 arranged a jacent the periphery of said ratchetwheel 91 and practically forms a continuation of the long tooth 91 andon which the pawl 88 is designed to re'- ciprocate bacl and forth.

A cam 96 is fixed to t-he hub of the ratchet wheel 91 on its front orouter face and is preferably made in the form of a disk having a recess97 formed in thel periphery thereof, and against the peripher of whichthe roller 64 above descrlbed is esigned to bear. This ratchet wheel 91is provided on its front or outer face with a plurality of laterallyextending studs of varying sizes, four being herein shown and numbered98, 99, 100 and 101, for a purpose to be described. A s ring 130 isarranged to engage and hol said wheel 91 against backward movement. Acomparatively small e for its spanning the AYnormall toothed wheel 93 isalso revoluble' on the' shaft 90.- The teeth-of this vwheel 93v aredesigned to be engaged by the pawl 89'when the extra courses are to beformed for making a longer foot or leg for a stocking as above referredto and as will be hereinafter described. A cam 102 (shown in Figs. 5, 10and 12) is secured to the hub of this wheel 93 adjacent its inner faceand is adapted vto be engaged by the roller 63 hereinbefore describedand the rotation of wheel 93 by pawl 89 causes said cam 102 to depressthe ever 62 which operates' through shaft 60, arm 59, link or arm 58',and arm 57 to turn the guard 53 under pawl 41 and thus throw the patternwheel out of operation. (See Figs.f2,5 and 69.) The pawl 89 is held outof engagement with the teeth o wheel 93 Aby means of a lever 126, thefree end of which -is arranged in the path of said pawl 89 to vpermit itto rock back and forth thereon without engaging the teeth of saidlwheel93, until said lever 126 is depressed by a cert-ain actuating mechanislnto be described, when it isl desired to have the pawl 89 operate thewheel 93 for knitting the extra courses. A small spring pressed pawl 129is arranged to engage the teeth of the wheel 93 and hold'it againstbackward movement.

The wheel 921s provided on it-s periphery 'with a plurality of teeth ofvarying sizes,

the opposite face of the wheel and are designed to engage a stud 91a onthe adjacent face of the wheel 91 for a purpose to be described.

Two members 131 and 132 operated by the'cams and headed studs on thepattern ring are mounted to move vertically through the base late 2 anda to said ase plate. T ese members which are similar in constructionandare shown clearly in Figs. 35, 36, and 42 are made in the form ofrods having lugs 131a and '1322* extending laterally from the lower endsthereof with the lower faces of said lugs inclined downwardly formingdogs or pawls at the lower ends of said rods. The upper ends of the rodsare cut away on one face to form fiat lever engaging surfaces to preventthe turning of said rods relative to the levers with which they areconnected. The rods are provided near their cut out upper ends withlaterally extending stops, preferably ide block 2 bolted made in the.form of ins 131" and 132b passed through said ro s and designed toengage lthe up er face of the block 2 for limitlng the ownward movementof said members. The cut out upper end of rod 1631 is`conn'ected withone end of a bar or level' 134,fulcrumed at 135, by means of a headedstud 131c the stem or shank of which exvtends through a longitudinallyextendin slot 134EL at oney end of the` lever 134 an through the upperend "of the rod 131, the slot providing for the tilting of said lever aswill be hereinafter described. This stud 131c has an annular flange 131darranged adjacent the head thereof which bears against the outer face ofthe lever end. The head of the stud 131c projects into the path of oneend of a vertically /swinging lever 149 and by means of which the lever134 is tilted as will be described. An upright bar 136 haviiig anolf-set formed therein extends upwardly at right angles from and is madeintegral with the lever 134 and together they form an inverted T-shapedmember. This upright bar is yieldably connected with the housing bymeans of a coiled pull spring 137 and which holds it and the lever 134in the tilted position shown in Fig. 35 and returns it to this positionafter it has been moved in the opposite direction by means to bedescribed. The upperend of this upright bar v 136 has a steppe head 138three steps 139,

140 and 141 being shown, the top or outerl end 142 forming another.These steps are adapted to be engaged by the free end of the longl armof the substantially L-shaped lever 142 (shown in Figs. 57 and 58).

' The horizontally disposed lever 149 hereinbefore referred to ispivoted interme-V diately of its ends to a post 150 projecting upwardlyfrom the base plate 2, and one end thereof extends under the head of thestud 131c and an L-shapedlug 151 extendsinclined arm at the endof-lever149 is arranged in the path of the studs carried by operated bysaid studs for tilting the lever 136 and is engaged by 'said studs onthe rotation of the ratchet wheel 92 whereby the lever 142 is caused todrop a distance measured by the step on the lever 136 brought under itto permit the pawl 87 to engage the desired tooth on the ratchet wheel92 as will be hereinafter more fully described.

The rod 132 has a lateral stud 132 on the ilat face of its upper endwhich extends through anelongated slot 133a near one end of a lever 133which end is. arranged to engage the lever 126 to depress the free endthereof out of the path of the pawl 89 to ing the end of the lever 133which bears against the lower face of the lever.126 and thereby raisingsaid end and depressing the other curved end thus removing it out of thepath of the pawl 89 and 'permit-ting said pawl to engage the teeth ofthe wheel 93. The-rotation of this wheel 93 brings the cam 102 thereofunder the roller 63 ou the lever 62 and depresses said roller carriedend which operates through the shaft 60, arm 59, link 58 and arm 57, toturn the guard 53 under the pawl 41 and thusy throw the pattern wheelout of operation. The

pawl 89 continues to turn the wheel 93 and the. knitting of the extracourses are knit until the cam 102 has been turned sutliciently topermit the roller 63 to run olf the other end thereof which operatesthrough the lever 62 and the links and arms connected therewith to turnthe guard from under the pawl 41 to again throw the pattern ring intooperation. On the vrotation 'of the pattern ring the studmoves out ofengagement with the pawl 132 and it is forced ldown by the pressure of-the lever 126 on the lever 133 under the tension of t-he spring 128 and'which also elevates the curved end of said lever 126 into the path ofthe pawl 89 whereby the knitting of the extra courses is stopped.

The lever 126 is ivoted at 127 tothe bearin or stud 61 see Fig. 2) andhas a bevele pawl-like nose 1263' at its upper free end which normallylies in the path of the pawl 89 and holds it out of engagement with theteeth of wheel 93 until said nose is depressed by the lever 133 forcingits other end upward, when the pawl 89 will drop into engagement withthe teeth and turn the wheel 93. A curved spring 128 has one end securedat 128a to the side of the housing and the other end thereof is engagedwith the free lower end'of lever 126 and is designed to hold the beveledupper end of said lever normally in the path of 'pawl\ 89 and also tolimit the downward movement of said lever. The levers 133 and 134 arepreferably pivotally mounted in a block 152 which is fastened to thebase plate 2 in any? suitable manner and is provided in its upper endwith spaced recesses or slots -153 and 154 in which said levers 134 and133 are pivoted as is shown in Figs. 35, 37 and 41 by a bolt 135.

A cam disk or drum 155 is fixed to the shaft 90 and is provided withsuitablelaterally extending cams as 156 which are adapted to engage thelpin 157d of the clutch $53, wifi operating lever 157 to rock said levera'nd shift the clutch 8 into engagement with the pinions 10 and 17,respectlvely, when desired, and which will be more fully brought out inthe description of the operation of the machine, (see F igs.V 1 and 4.)l

A needle elevating switch cam operating lever 158 is fulcrumed at 159 toa stub shaft 160 secured to the frame 1 and the free end of this leverprojects into the path of the laterally extending cams as 161 and 161carried by the drum or cam disk 155 which are designed to operate theneedle elevating switch cam for raising and lowering the needles duringthe formation of the heel and toe as will be hereinafter more fullydescribed in the description of the A,operation of the machine. Thislever 158 is construct-l ed inQthe form shown in Figs. 55 and 56 and alink 162 is pivotally connected at one end with the lever 158and at itsother end to a bell crank lever 163 which is fulcrumed at 164 to a stubshaft 165 which ex"tends laterally from the frame 1 and a spring 166 isconnected at one end to the long upriofht arm of the lever 163 and atits other end.J to the frame 1 and is designed to hold the free end ofthe lever 158 in engagement with the 'cams of the cam disk 155. A link167 is pivotally connected with the free end of the long upwardlyextending arm of the lever 163 and at its other end with a bell cranklever 168 connected with a needle elevating switch cam.

Secured to the shaft 90 at the opposite end thereof. from the beltshifting cam disk 20 is a cam disk 180 by which the 'picker operatinglever 181 is actuated (seeFig. 1), and which is connected to operate thepickers in a well known manner such, as is shown in the Hemphillpatents, Numbers 933,443, dated September 7, 1909, and 934,969, datedSeptember 21, 1909. This cam disk 180 is constructed as shown in Figs.66 and 67 and the picker operating lever, the toe 182 of which extendsinto the path of the cams on said disk 180, isconstructed as shown inde- -tail in Fig. 68.

When it is desired to knit a different colored tip for the heel and toe,(see Figs. 1, 60 and 61,) a threaded pin 173 is adjusted in the upturnedend of lever 170 in position to come in the path of the stud 31a on thedepression of the end 172 by one of the studs 155a or 155b on the camdrum to limitA the depth the pin 24 may extend .into the recess 32 or 33in the pattern ring 23 and thus control the outward swing of the raceway30 thereby operating the properk nger for throwing into o eration thedesired yarn changer for supplying the color desired for the tip. Aspring 171'is connected with the lever 170 and the housing, to returnsaid lever to normal position after it is operated. When it is desiredto have the tip of the tern ring v23 moves.

same color as the heel o r toe, the screw pin 173 is adjusted to itsextreme inward limit A for holding the lever 25`against movement whenthe pin 24 passes over the recess 32 or 33 in the periphery of the ring23. A jam nut1''3a is arranged to hold the pin 173 in adjusted position.The lever 170 has a lug or projection 174 adapted to engage. a stop inthe form of a lug. 191 on the bracket 190 for limiting the inwardmovement of said lever.

It is to be understood that during the formation of the leg and foot,the needle cylinder rotates and when forming the heel and toe itreciprocates one half of the needles only being in operation, during theknitting of the heel and toe.

In the operation of this machine, the parts of which are shown at theirstarting or initial position for beginning the knitting of the leg, seeparticularly Figs. 1, 2, 3, 5 andv35, the driving belt 18 is operatingon the fast pulley 3 (as shown in Fig. 1) and the clutch 8 is engagedwith the clutch member 10 of the gear 10 to provide for the rapidrotation rests on the long arc-shaped cam 34 about midway thereof withthe stud of pin 131 resting on the guide block, as shown in Figs. 3, 4and 35, with the end of the pawl or lever 142 resting on or engaging thestep 140 of the head 138 of the upright tilting lever 136 and theoscillating pawl 87 engages what are herein termed the `idle teeth 103,104 and 105 of wheel 92, said wheel during the actuation of these teethbeing idle or in other words operating no mechanism. As the knitting ofthe leg proceeds the cam 34 on the pattern ring 23 moves from under thepawl rod 131 and said rod is held in this position by its pin 131aresting on the guide block, the lever 136 having been tilted to bringthe extreme end or step 142 of the y,head 138 in engagement. with thelever 142 bringing said lever 142 under said pawl 87 and therebythrowing the' actuating wheel out of operation. As the pattern ringrotates the various yarn changers are operated to produce the variouspredetermined stripes by the pin 24 under the point of which theperiphery of the pat- F or instance, when a certain notch or recess inthe periphery of said ring comes opposite the pin 24, said pin dropslthereinto and the upper free end of the lever 25 is moved outward intoposition toguide the finger 80 into engagement with a pin of one of theyarn changer operating fingers, whereby the upper end of said finger ismoved backward to bring its toe 73 into engagement with the pawl member74, thus relieving the free end of lever 68 from engagement with the lugat the upper end of said finger and releasing the tension of the wirewhlch connectssaid lever 68 with its-rct a notch of Vdiderent depthinthe periphery.

spe'ctive yarn changer and permitting the spring of said yarn changer tothrow 1t into operation. At the same time theroller 78 engages lever 25and lifts the pin 24 out of the notch and the yarn thrown in continuesin operation until the pin 24 again drops into of the pattern ring, whenthe above described operation is repeated, the linger 80, however,engaging the pin of a dlerent finger for throwing in another yarn. rllhecam 36 on ring 23- then passes under the pawl rod 131 and tilts lever316 inpositi'on to bring its ste 141 into engagement with the lever 142,t ereby permitting the pawl 87 to engage the tooth 106 and turn theshaft 90 to bring the slowing-up mechanism into operation preparatory tothe throwingv of the needles onto the heel. The raised end or lug 36 ofthe cam 36 lifts the rod 131 higher and tilts the lever 136 backward topermit 'the lever 142 to drop onto the lowest step 139 and allows thepawl 87 to engage the tooth 107 which turns the shaft and actua-tes themechanism to throw the machine on the heel and simultaneousl the camdisk or drum 155 is turned su ciently to shift the clutch 8 to the leftinto engagement with the clutch member of the gear 17 for the formationof the heel. At the 'same time the yielding pin 123 engages the stud 91aor the inner face of the ratchet wheel 91, whereby a jerking movement isimparted to said wheel 91 turning it sufficiently to permit the pawl 88to engage the small teeth of said wheel 91 and actuate the wheel.Simultaneously the cam 96 on the hub of the wheel 91 is turned inposition to engage the roller 64 on the end of the lever 62 and therebyturns the guard 53 to cause it to raise the toe of pawl 41 out ofengagement with the ratchet wheel which actuates the pattern ring andwhereby the said pattern wheel remains stationary. The feedingof the camdisks and the toothed wheels is now accomplished by the ratchet wheel91, it having been brought into position for engagement by the feedingpawl 88 as above described.- The stud or screw 98 on the outer face ofthe ratchet wheel 91 is now brought into engagement with the upperinclined end o f arm 151 of the lever 149 and depresses. the oppositeend thereof i which extends under the laterally extending head 148 ofthe stud which connects they slotted end of the lever or bar 134 withthe upper end of the pawl rod 131. This movement of thelever 149 tiltsthe upright lever 136 and permitsthelever 142 to drop onto the step 141of head 138 and permits the pawl 87 to engage'the tooth 108 which turnsthe shaft 90 a suiicientv distance to turn the cam disk 155 to bringthexstud 155 thereof into engagement with-the end 172 of the lever 170for throwing the desired color in to form' the heel tip. They stud ,99on the eeaaes ratchet wheel 91 is now engaged with thev arm 151l oflever`149 and tilts the upright 136 a sufficient distance to permit thelever 142 to drop onto the step 140 of the head 138 of the lever 136 andpermits the pawl 87 to engage the tooth 109 and turns the shaft 90 andthe picker operating cam disk 170 to operate the lever 171 to take downa portion of "the needles, two needles being drawn down at a time oneach reciprocation thus forming the gore in the heel. r1`he smalll stud100 next engages the arm 151 ofthe lever 149 thereby tilting the lever136 to permit the lever 142 to drop onto the step 141 and allowthe pawl87 to engage the tooth 110 which actuates the mechanism for taking thetip out of the heel, As before stated, during the above describedoperations, the pattern ring is stationary. rl`he large stud 101 nowengages the 151 of the lever 149 thereby tilting the upright lever 136into position to permit the lever 142 to drop onto the step 139 of thehead 138 and allow the pawl 87 to engage the tooth 111 thus operatingthe mechanism to throw the machine ed' from the heel onto the foot, theclutch 8 having also been shiftedfrom the left to the right to cause itto engage with the member 10 of the gear 10 to provide for the rapidoperation of the needle cylinder during the formation of the foot, itbeing understood that the belt has been shifted from the slow pulley 4onto the fast pulley 3 for the formation of the foot. At the same time,the ratchet wheel 91 and the cam 96 carried thereby have made onecomplete revolution and the roller 64 drops into the notch 97 thereofwhich, through the arm 62 and the levers connected therewith, turns thecam or guard disk 53 to bring the recess therein 0pposite the pawl 41 topermit said pawl to again engage the teeth of the ratchet wheel 50thereby throwing the pattern ring 23 again into operation for theformation of' the foot.

After the foot has been completed, the cam 35 comes in contact withthepawl-shaped end of the rod 131 thereby raising said rod and tiltingthe lever 136 to permit the lever or pawl 142 to drop onto the step 140and allow the pawl n87 to engage the tooth 112 to operate the mechanismfor slowing up the machine. The further movement of the patternring 23causes the upwardly extending lug 35 thereof to further raise the rod131 and tilt the lever 136 into position to permit the lever 142 to droponto the step 139 thereby permitting the pawl 87 to engage the -onto theslow' pulley 4- for operation during the formation of the toe. At theend of this
